我在水管工中发出POST请求时当前出现此错误:
Warning in if (stri_startswith_fixed(body, "{")) { :
the condition has length > 1 and only the first element will be used
Warning in if (stri_startswith_fixed(qs, "?")) { :
the condition has length > 1 and only the first element will be used
这就是我的功能:
#' Get results from Two Sample t-test
#' @serializer unboxedJSON
#' @param group:character The group col you would like to group data by
#' @param variable:character The variable you would like to be compared between groups
#' @post /twosamplettest/<group>/<variable>
function(req, group, variable) {
data_as_df <- fromJSON(req$postBody)
results <- t.test(get(variable) ~ get(group), data=data_as_df)
group_mean_df <- extractGroupsAndMeansFromTTestResults(results)
test_results <- list(pvalue=results$p.value, group_stats=as.data.frame(group_mean_df)))
test_results
}
即使是这样简单的事情也会给出相同的警告:
#' @post /test
function(message){
"Testerino"
}
该请求获得了有效的响应,除了在控制台中针对每个提出的请求显示的丑陋警告消息之外,其他所有内容都很好。
有任何解决方法的想法吗?

结果证明,这与postBody中使用的JSON有关。如果JSON包含未转义的选项卡或换行符,则会引发警告。

在水管工仓库中有一个issue已关闭,在最新的1.0.0版本中不再应该发生这种情况。
